Here are the correct answers for your homework assignment on Earth's Movements in Space.
1. What is an imaginary line that goes through the center of an object, such as Earth?
*
Reasoning: An axis is the invisible line around which a planet spins. The Sun and Moon are objects in space, not lines.
*
Answer: d. Axis
2. What is the spinning of Earth on its axis called?
*
Reasoning: Rotation is the word used for spinning around an internal center (like a top). Revolution is moving around something else (like Earth going around the Sun).
*
Answer: b. Rotation
3. How long does it take for Earth to make one complete rotation?
*
Reasoning: One full spin of the Earth creates one day and one night cycle, which takes 24 hours.
*
Answer: d. 24 hours
4. What causes the apparent movement of the sun across the sky?
*
Reasoning: It looks like the Sun moves from east to west, but actually, the Earth is rotating towards the east. This rotation makes the Sun appear to move.
*
Answer: c. Rotation
5. What is the term for a group of objects or events that repeat in the same order?
*
Reasoning: When things happen over and over again in a predictable way (like day following night), it is called a cycle.
*
Answer: d. Cycle
6. Which part of Earth experiences day when it faces toward the sun?
*
Reasoning: Daylight happens when sunlight hits the Earth. Therefore, the side facing the Sun gets the light.
*
Answer: c. The side facing toward the sun
7. What happens when the Northern Hemisphere tilts toward the sun in June?
*
Reasoning: When a hemisphere tilts toward the Sun, it receives more direct sunlight and has longer days. This causes summer.
*
Answer: b. Summer
8. What causes the change in seasons on Earth?
*
Reasoning: Seasons change because Earth revolves (orbits) around the Sun while staying tilted on its axis. This tilt means different parts get different amounts of sunlight throughout the year.
*
Answer: b. Revolution
9. What season occurs in the Southern Hemisphere when it’s summer in the Northern Hemisphere?
*
Reasoning: The hemispheres are opposites. If the North is tilted toward the Sun (Summer), the South is tilted away from the Sun (Winter).
*
Answer: c. Winter
10. How does Earth’s tilt affect the angle of the sun’s rays it receives?
*
Reasoning: In winter, the Earth is tilted away from the Sun. This causes the sunlight to hit the ground at a slant, spreading the energy out over a larger area, which makes it feel weaker and colder.
*
Answer: a. It spreads out the rays in winter.
